How to change the FOV in Fallout 4 and other tweaks

As with most PC games there’s a certain amount of tweakage that can be done to improve the experience depending on hardware and Fallout 4 is no exception.

The first thing most of you will want to do is change the FOV which is set at 80 by default. 90 is usually a good starting point for most us however. So how do you do it? With some ini file editing of course.
